Put the power bar on the game scene

Finally we have came to the last chapter of this pygame project, in this chapter we will put three things on the game scene, a text which indicates what is the power level of the player, a game level indicator as well as a power bar which shows the power level of that player in the graphic form. We will need to edit three files in order to create such a mechanism.

The first file we need to edit is the game manager file where we will reactivate the score manager class.

        self.level_text = "         Level " + str(self.level_manager.get_level())
        self.text = self.font.render(self.score_text+self.level_text, 1, (255, 255, 255))
        self.scene.blit(self.text, self.rect)
        self.scene.blit(self.power_surface, self.draw_power_pos)

If we run the above program below is what we will expect.

There you have it, we have finally finished this pygame project. Although I will not post any new game features of this project on this website anymore I will continue to develop this game. The features that I am planning to include in this game in the future are as follows:

  1. Boy shoots a missile to destroy the enemy.
  2. The enemy shoots a missile to wipe out the boy.
  3. A few new enemies will be introduced into the game.
  4. More game levels.
  5. More type of manas or maybe treasures that will increase the game point of the boy.
  6. Maybe the boy will need to save the life of someone during the game which will help him to gain the game point.

Anyway, although I will no longer update this project I hope you will gain something from this project and go ahead and create your own pygame project even-though I will no longer update those new features anymore on this website.

After this chapter, I will create another new pygame project and will post on this website about two to three times a week but not often because I will need to take care of the offline business which will bring me some daily income. I would like to go full time to develop the game and create a daily post but I really need to earn income to survive so I have decided to concentrate more on the offline business from now onward. If you want to help me out then maybe you can make a donation to this site through the donation button on the sidebar of this website. Thank you in advance. See you all again probably next week on this same website.
